V (~200): Just sat down at the table. No history with Hero.
H (covers): Unknown to V.

3 limps, Hero at HJ limps with 77, CO calls, BTN calls, SB calls, V in BB checks

Flop (16): 7 5 2 sss

V leads out 15, folds to Hero who 3b to 40, V shoves 180 more to call, Hero?

Are you serious dude? You got top set! Insta-call that all in, your getting your money in good. Villains range here consists of flush/straight draws, you could boat up on turn or river keep in mind. 55 or 22 is also possible due to the preflop limp action. 72-52 seems unlikely but also can be possible if villains are loose enough. Easy call, never fold in this spot.

I wouldn't call. with no reads, he is always going to have spades here.

lol

Your limp pre is horribad.
* You very likely have the best hand
* If you hit a set (like here), you'll have a ridiculously small pot to build on, requiring a monster overbet (like here).

Raise to $7-8 here. Punish the limpers. Charge the draws.

As played, you've gotta figure you're behind here. I'm expecting him to have a made flush, mabe drawing to a straight flush. Whether you call here depends on how much gambool you've got in you. If we were playing a bit shallower, I'd probably call, but I'm a bit of a nit, so I'm likely folding.

Pokerstove has you at about 35% equity vs a made flush btw (which he has here like 98% of the time).

Folding a set at 1/2nl for 100bb is 99.9% of the time going to be wrong.

$180 into a $96 means you need 39.5% to call.

It's a call even against the worst case range of {all 78 flush combos, 55,33}. Once you start adding a few combos of stuff like 75, As7o, As5o, 9s9 (and removing AsKs, AsQs) it becomes an easy call.

Snap call. I wouldn't even have to think about it.

Anguished fold, especially with no read on the guy. If you learn later that villain is capable of making that shove with As-x, then its a call.

Not a snap call, but more of a crying call.

If you break it down to 22 55 and flopped flushes is a call all day long. Come on now even the math is right with 2 cards to come.

I agree with bulls that you should raise preflop however a raise to 7 or 8 is a joke with 3 limpers. They will all call for sure and you are inducing more calls from the players on the button and the blinds because it will be a bigger pot and lots of 1-2 players love the pots that have smallish raises with lots of players in them. Then you must flop huge and the majority of the time you are just wasting the raise. Raise more or if you don't want to do that, limp.

I don't think a limp here is that bad, figuring you're likely getting called by most limpers and then seeing overcards on the flop, putting 1bb in here to then stack someone who cant fold top hair once you hit your set is a good play.
98% is ridiculous, i think you're against a made flush here much less often, especially at a 1/2 table. There's only 2 overpairs that likely limp pf (only really seeing 88, 99 gii here if they have a spade in their hand too) but there's more than enough Asx / two pairs / 55 / 22 to figure you're best here. Remember he checked his option in the big blind so could easily have 52o. GII --> STACK CHIPS

I don't think even 1/2 fish are 3bet shoving dry straight draws on a monotone flop. 3 of the same suit without one of that suit in their hand looks far too scary. Although I definitely wouldn't be surprised to see a combo draw here, like 6x8s.

Anyone saying to fold needs to do some actual math.
Preflop can go either way. In games where people will pay off a lot limping is fine to get a bunch of people in.

Yeah, this is the easiest snap call ever.

I'm not doing the math, but you can imagine even with an incredibly strong villain range - 3 combos of 22, 3 combos of 55, a bunch of made flushes - we're calling. It's also not impossible he has a naked draw + pair, like As7x, but it doesn't even matter. This is not remotely a close situation.

OK I got bored and did some math. Against a range I tossed together of 6 lower set combos and 33 made flushes, we have 46% equity.

Come on guys.

FYI, that's a raise, not a 3-bet.

You know we have 35% equity against a made flush, right?

If villian turned over his hand and showed you a made flush we have the odds to call.

Range, pokerstove, pot odds, snap call.

This makes basically no sense. Unless you mean an unknown LLSNL player can only have spades here. Which isn't right imo.

with top set its still a call for reasons mentioned. I mean he could also have just the naked As or a combo draw. Not a snap call by any means. Raise pre is pretty bad even with position unless you're pretty sure you can get it heads up or two players without having to raise to more than $18 or so. With one limp raise pre for sure l, two limps it close, but 3 or more just limp behind

And no you're not punishing limpers at all when you raise to $8 after limps. You're just bloating up the lot for some monkey to win where you will hate the flop 88% of the time. Even if you flop an overpair you could still be behind as people flat 88-JJ all the time and someone could flop some bs two pairs

Actually we wouldn't. We only have 35% or so whereas we need 39% just to breakeven. Sure if he showed a flush we can fold. But we beat sets and big draws too so this is a call here with those odds

If I were to raise pre I would raise to $20 to try to get it heads up
